Turn On or Off the Eye Comfort Shield (Blue Light Filter) auf Samsung
Blue light from a phone display suppresses melatonin and keeps your eyes working harder in low light. Samsung addresses this with the Eye comfort shield, a display filter that shifts the screen toward warmer tones and reduces the amount of blue light reaching your eyes.
The feature sits inside the display settings rather than accessibility settings, even though it is often searched for under that name. It can run permanently, on a fixed schedule, or only overnight, and you can adjust how strong the effect is.
Turn it on or off
Go to Tap on Settings ➔ Tap on Display ➔ Enable or disable Eye comfort shield. Toggling the switch applies the warmer tint immediately across the whole screen, including most apps.
If colors look washed out for photo editing or design work, disable the filter temporarily instead of lowering the intensity slider, since a partial filter still shifts colors slightly.
For sleep-related complaints, a scheduled activation in the evening hours is usually more effective than leaving the filter on all day, since your eyes only need the reduced blue light shortly before bedtime.
